Underlag til formalet galvaniseret stålspole

Koldvalset stålspole

Color rolled steel coil—— the substrate for Formalet galvaniseret stålspole. Med et glat og smukt udseende af koldvalset-stålspole. Men alle mindre ridser i overfladebelægningen vil udsætte det koldt-valsede underlag for luften, hvilket hurtigt udsætter jernet for at generere rust. Derfor kan den kun bruges til midlertidige isoleringsforanstaltninger og indvendige materialer med lave krav.

Varmgalvaniseret stålspole

Hot-dip galvanized color-coated sheet has the protective effect of zinc. However, the surface's organic coating can also be insulation and protection, preventing rust, and the service life is longer than that of hot-dipped galvanized sheets.

Galvalume stålspole

The composition of galvalume steel coil is 53 percent aluminum, 43.5 percent zinc, and 1.5 percent silicon, named  55 percent Al-Zn. According to the data, the comprehensive anti-corrosion ability of 55 percent aluzinc is four times that of galvanized with the same thickness.
